WALO's Dense Asphaltic Concrete (DAC) lining system is perfect for lining reservoirs, canals and irrigation systems as it is non-toxic, impermeable, very strong and still flexible enough to withstand the stress of large volumes of water being pumped in and out every day.

Large ships travelling though canals cause powerful waves but canals lined with DAC can withstand the pressure they create. Long side slopes in these containment systems are not a problem either, as WALO can line slope lengths of 120m or more using specially designed machines which have no need for regular joints – often a major problem for barrier systems.
